All the complexity with the different ways that CMAKE_C_COMPILER and CMAKE_C_COMPILER_ARG1 can be set are no longer needed, it's all handled by the toolchain wrapper now. Note that it is still necessary to handle this for the host build.

# CMake package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for CMake packages. It should be used for all
|
|
# packages that use CMake as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this CMake infrastructure requires
|
|
# the .mk file to only specify metadata information about the
|
|
# package: name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default CMake behaviour. The
|
|
# package can also define some post operation hooks.
